WINDOW FRAME Filed March 11, 1929 l/VVENTOR CHARLES DRJLL' I! ll :1 l:

Patented Mar. 31, 1931 PATENT OFFICE CHARLES DRILL, OF ST. LOUIS, MISSOURI WINDOW FRAME Application filed March 11 My invention relates to improvements in window frames, and has among its objects the production of such frames which shall be simple and sturdy in construction, convenient in operation, and eflicient and satisfactory for use wherever found applicable.

Another object of my invention is to provide a frame of the kind described, in which either the inner or outer window may be swung inwardly, into the room, relatively of the frame, so that the same may be cleaned without the neccessity of sitting or stand ing outside of the window for this purpose.

Another object of my invention is to pro- 5 vide a hinge member or pivot for this swinging movement, which shall serve the additional purpose of reinforcing the windows and making them extremely strong and whereby they will last for long periods of time.

Another object of my invention is to so construct such frames, so that access may be had to the pulley cords or weights without the necessity of removing either the inside or the outside window stop pieces.

Many other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art to which this invention appertai'ns, from the disclosures herein given.

To this end, my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and uses mentioned, and more particularly pointed out in the claims.

1929. Serial No. 345,976.

Referring more particularly to the drawings, wherein I have illustrated a preferred embodiment of my invention, A indicates the wall of a room in which a window is placed. The window frame has a top or head end 1, a bottom end or sub-sill 2, and the side jambs 3, the latter providing the inside and outside pulley-stiles and 5, respectively. As shown, the construction is of a checkrail window, in which the pair of windows are double-hung and slidablevertically within the pulley-stiles. The pulley boxes at the opposite sides of the frame are formed of the pulley-stiles or side jamb pieces, inside and outside trim pieces 6, and 7 respectively, (15 and a piece 8 parallel to and spaced from the stile 3.

The pulleys are mounted at the upper end of the frame, on opposite sides, one pulley in each stile, as at 9, so that the windows 79 may be double-hung. The sash-cord 10 and weights 11 co-operate with the pulleys in the usualmanner.

A parting rail 13 extends longitudinally H on each side jamh, between the pair of pulleys, on each side, and dividing the jamb into the inside and outside pulley-stiles 4 and 5 respectively. An inside stop 14 extends parallel to the parting stop and spaced there- 7 from a distance substantially equal to the thickness of the rail material out of which the windows are made, this stop being preferably removably secured to the jainb by screws, nails or other securing means. An outside stop 15 is similarly positioned on the j amb, parallel to the insidestop and parting rail, and adapted to provide a vertical guideway together with the pulley-stile and parting rail, in the well-known manner.

Access to theinterior of the pulley-boxes is generally provided, by placing a closure plate over an opening through the pulley stiles, there being one opening through each pulley stile, and with the stops normally exn tending over and covering the lines of juncture of the cover and stile, so that it is necessary to first remove the stop before removing the cover.

This method is unhan-dy and requires much time, and in order to avoid this, I so 1100 struct the parts that it is not necessary to first remove either stop or parting rail in order to provide access to either of the pulley weights. I cut out a portion of the side jambs at 16, this opening extending to either side of the parting rail from adjacent one stop 14 to adjacent the other stop 15, and extending vertically the desired distance. A single closure plate 17 fits into this opening and forms part of the pulley-stiles and the parting rail, as shown, said cover being removably held in position by means of screws or the like. Obviously, access may be had to the pulley-weights without removing the stops.

As shown, the windows are double-hung, the lower or innermost window being indicated at B and the top or outermost window being indicated at C. Each of these windows is formed of a top, bottom and side rails, 18, 19, and 20, respectively, the same enclosing the usual pane of glass or light.

. These windows are not directly suspended by the sash-cord, but on the contrary, they are carried upon intermediate means, which I term as slide elements or members 21, there being a slide element interposed between each side of the window and the adjacent pulleystile.

Each of the slide members is substantially of the same length as the window with which it co-operates, and is provided with a shoul dered edge 22 to form a stop. as will be hereinafter described, this shoulder preferably extending beyond the outer edge of the stop members 13, 1 1 and 15, the main body portion of the slide element being of substantially the same thickness as said stop members, so as not to be unduly visible when in place and the stop members affixed in position.

The lower or innermost window is supported by and movable with the pair of sliders in the inner stiles and the other window is similarly supported by the pair of sliders in the outer stiles, these windows being hinged or pivotally movable with respect to their co-operating sliders. The pivot means for this purpose may be a metal rod or bar. of the desired thickness, extending along the lower rail 19 of the window, as at 23, preferably within a groove 24 therealong and thence bent upwardly at either side at 25-25 to form a substantially U-shaped element the vertical extensions 25 lying within grooves 26 of the sliders. The sashcord is secured to the upper ends of the portions 25.

Any suitable means may be used for liolding the U-bar in place in pivotal engagement with the bottom of the window rail, as for example, by the angle-shaped element 2728 which overlies the meeting edges of the side and bottom of the rail, said element being provided with an aperture through which the bar extends. A metal plate 29 may be inserted into a slot extending upwardly from the bottom of the slider element, said plate being apertured to receive the bar therethrough.

The pivotal connection thus provided is simple, efficient and economical, and has the further function of serving as a reinforcement for the bottom rail of the window, as it is obvious that any pull on the window rail must be transmitted through said metal U- bar, and thereby there will be no likelihood of pulling the bottom rail of the window away from the side rails, as sometimes occurs when pulling down upon a window that is or has become defective. The sash-cords are connected at their ends to the upper ends of the U-bars, so that the entire weight of the windows are carried by the sash-cords through the metal bars, the slider elements themselves being left to perform their sliding function only and not to carry the weight of the Windows.

Both windows are turnable through almost a full 180 are, so that in inclement weather the windows may be substantially completely reversed so as to leave a minimum of air space between themselves and their adjacent sliders while washing said windows.

In order to prevent the accidental swinging of the windows, latches or looks 30 may be provided, said locks being of any preferred construction, said locks removably locking the windows and sliders together against pivotal movement, but not against sliding movement together in the stiles. Metal sleeves 31 may be placed in the wooden portions, and through which said locks extend.

In normal position, with the windows in closed positions, the top edge of the lower or inner window will be substantially flush with the upper edge of the bottom rail of the outer or top window, as is usual. Hence, some special means must be provided whereby the top window can be swung inwardly relatively of the frame when it is desired to clean the top window.

. To accomplish this purpose, I have recessed the head of the window frame, to provide a slip-head 32, this opening extending upward ly into the frame, above the inside pulleystile as shown, so that the bottom or inside window and the sliders carrying the same may be moved upwardly so that said slip head or recess 32 receives the upper portions of the sliders and the inside window. With the inside window in this position, and the outer or top window lowered, there will be a space between the top of the lowered outer window and the bottom of the raised inner window, thereby enabling the lowered outer window to be pivotally swung about its lower edge in the same manner as was the inner window.

Thus it is seen that I have provided a construction in which either the top or bottom window may be swung inwardly and washed or cleaned, without the necessity of cleaning from the outside of the room in which the window is located.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, except as limited by the claims.

What I claim as new and desire to secure by Letters Patent is:

1. The combination with a window frame, of a counterbalanced hung window therein, and means for pivotally swinging the latter about its lower edge inwardly relatively of the frame, said means comprising slides at either side of the window and slidable in said frame, and window-supporting means on said slides and pivotally connected to said window at the lower edge of the latter, said last-mentioned means comprising a metal rod extending along said lower edge and bent upwardly at both ends, the ends of said rod being adapted to be secured to the counterbalancing means and resist the strain therefrom.

2; The combination with a window frame having double pulley stiles and pulley weights at their sides, of an upper and a lower window, slide elements interposed between said stiles and the side rails of said windows, and a metal rod extending substantially along the bottom rail of each window and upwardly along the adjacent slide elements for pivotally supporting said windows by said slides and to which. the pulley weights are adapted to be secured whereby the strain from said weights will be taken up by said rods.

3. The combination with a window frame having a window hung therein, and counterbalancing means therefor, of a reinforcing element extending along the lower edge of said window frame and connected to said counterbalancing means for resisting the strains transmitted through the latter.

4. The combination with a window frame having a window slidably and pivotally hung therein, and counterbalancing means therefor, of means for pivoting said window along an axis adjacent the lower edge of said window so that said window may be swung about said pivotal axis, and an elongated reinforcing element extending along said lower edge of the window to form said pivot, and connected to said counterbalancing means to take up the strain therefrom.

5. The combination with a window frame having a window pivotally hung therein, and counterbalancing means for permitting said window to slide in said frame with ease,

from the latter.
